• Looking for an extended version of Lightbox

  - by itsandy

  Hi All, I am not sure how to put this, maybe I'm not able to search it properly I'm not sure what is it called but I am looking for a script which is a kind of an extended version of lightbox script. I want to place some images in my website which when clicked opens as lightbox and can go next and previous but the trick is the next images have to be sub pics of the pic which is displayed. So lets say I have "a" "b" "c" ....images shown on my website but when some clicks "a" the image "a" opens but then when he clicks next image {{ with the help of the lightbox script }} he goes to "a.1" "a.2" ....and so on for image "b" ...... Can anyone help me finding this script I have seen i somewhere bu not sure of the search term. Many Thanks

• Outputing resized animated gif to browser using imagick

  - by Freeman

  I intent to resize an animated gif and outputing it to the browser on-the-fly. My problem is that when I save the resized image it is of good quality, but if I echo it to the browser it is of poor quality and the animation is removed. Here is the code:` header("Content-type:image/gif"); try { /* Read in the animated gif */ $animation = new Imagick("images/nikks.gif"); /*** Loop through the frames ***/ foreach ($animation as $frame) { /*** Thumbnail each frame ***/ $frame->thumbnailImage(200, 200); /*** Set virtual canvas size to 100x100 ***/ $frame->setImagePage(200, 200, 0, 0); } /*** Write image to disk. Notice writeImages instead of writeImage ***/ //$animation->writeImages("images/nikkyo1.gif",true); echo $animation; } catch(Exception $e) { echo $e-getMessage(); } `

• extend web server to serve static files

  - by Turtle

  Hello, I want to extend a web server which is only able to handle RPC handling now. The web server is written in C#. It provides a abstract handler function like following: public string owsHandler(string request, string path, string param, OSHttpRequest httpRequest, OSHttpResponse httpResponse) And I wrote following code to handle image files: Bitmap queryImg = new Bitmap(path); System.IO.MemoryStream stream = new System.IO.MemoryStream(); queryImg.Save(stream, System.Drawing.Imaging.ImageFormat.Bmp); queryImg.Dispose(); byte[] byteImage = stream.ToArray(); stream.Dispose(); return Convert.ToBase64String(byteImage); And I test it in the browser, the image is returned but the image dimension info is missed. Shall I add something more to the code? Or is any general way to server static files? I do not want to serve it in a ASP.net server. Thanks

• Swapping UIImages causing 'unrecognized selector sent to instance' ?

  - by user158103

  Error: [__NSCFDate drawAtPoint:]: unrecognized selector sent to instance 0xd251e0 Termininating app due to uncaught exception 'NSInvalidArgumentException' Scenario: for the most part this works. But I notice this error, even on the simulator, when I swapping UIImages, slowly, but consistently. For example, I have a retained reference to a UIImage that im drawing. By the click of a picker control I am changing the face image (this occurs in another view-controller). I can consistently recreate this error by continuously changing the faces. It usually crashes at about the 4th swap or more. My theory: It's not loading the image, therefore the image reference is nil. I know ive read a bit about UIImage being cached, so I wouldnt think im running out of memory. Any ideas? Thanks!

• jquery form select (if exists in $_POST)

  - by SoulieBaby

  Hi all, I'm trying to redo this in jQuery: <script language="JavaScript" type="text/javascript"> var thisIsSelected = '<?php echo $_POST['image']; ?>'; var sel1= document.getElementById('image'); sel1.value = thisIsSelected; </script> But I seem to keep breaking it lol Basically I want jQuery to check if $_POST['image'] exists and if so make it selected on the form. I'm assuming if it's possibly with javascript, jquery can do it easier ;)

• CSS [custom?] attributes

  - by Michael

  radio[pane] { list-style-image: url("jar:resource:///chrome/classic.jar! /skin/classic/browser/preferences/Options.png"); } radio[pane="prefpane-appearance"] { -moz-image-region: rect(0px, 32px, 32px, 0px); } radio[pane="prefpane-appearance"]:hover, radio[pane="prefpane-appearance"][selected="true"] { -moz-image-region: rect(32px, 32px, 64px, 0px); } Can anyone explain a syntax of this css, particularly what is pane.. I couldn't find such attribute for radio element in context of XUL. So I guess it's some custom attribute? If it is, then how it is evolving through the lines, first declaration, then several assignments? It has also selected, which means can have multiple custom attributes? How can those attributes be used later?

I've tried playing with the artsexylightbox css file but couldnt get it to work in both browsers. does anyone can say why is the difference? I suspect that the browsers treat the absolute,relative orders differently. please help:(

• Override transparency color when converting transparent PNG to JPG

  - by Alexander Malfait

  I'm using Dragonfly to generate thumbnail images in a Rails app. I'm serving all picture images as JPG's. Now the client is uploading transparent PNG files, like this one: http://www.ibanez.co.jp/products/images/eg2010/ART120_TRF_12_02.png Dragonfly uses RMagick to convert these images to JPG. The problem is that it converts the PNG images to JPG with a black background, and my site's design requires a white background. I've tried to override it like this: encoded_image = Magick::Image.from_blob(image.data).first if encoded_image.format.downcase == format image # do nothing else encoded_image.format = format encoded_image.background_color = "white" encoded_image.transparent_color = "white" encoded_image.to_blob end But the produced JPG images still contain a black background. Does anyone know how to beat RMagick into using a white background when converting the transparent layer? I know I could just serve as PNG, but then the images are 10 times as large, and the site is already pretty bandwidth heavy.

• What libraries are available for manipulating super large images in .Net

  - by tpower

  I have some really large files for example 320 MB tif file with 14000 X 9000 pixels. The operations I need to perform are basically scaling the images to get smaller versions of it and breaking the image into tiles. My code works fine with small files and I use the .Net Bitmap objects but I will occasionally get Out of Memory exceptions for larger files. I've tried using the FreeImage libraries FreeImageBitmap but have the same problems. I'm using something like the following to scale the image: using (Graphics g = Graphics.FromImage((Image)result)) { g.DrawImage( source, xOffset, yOffset, source.Width * scale, source.Height * scale ); } Ideally I'd like a third party library to do all the hardwork, but if you have any tips or resources with more information I would appreciate it.

• Flashing and closing PyS60 SIS

  - by Matrich

  I created a py script for S60 2nd Edition FP3 with a background image, database, sound files which are stored in a folder on c drive. After several hours, I have managed to convert it into sis which I sent to my mobile phone. First, I installed the sis on the external memory and it failed to work. I read online that it should be on the same drive as python runtime. So I installed it on phone memory but it just flashes and then closes. I made another sis with a database and it worked so I suspect it could be because it cant find the background image and sound files in the folder. How can I know the cause of this? Also, how can I include the background image and sound files with the sis so that they are automatically installed when installing the sis file?

• Send a "304 Not Modified" for images stored in the datastore

  - by Emilien

  I store user-uploaded images in the Google App Engine datastore as db.Blob, as proposed in the docs. I then serve those images on /images/<id>.jpg. The server always sends a 200 OK response, which means that the browser has to download the same image multiple time (== slower) and that the server has to send the same image multiple times (== more expensive). As most of those images will likely never change, I'd like to be able to send a 304 Not Modified response. I am thinking about calculating some kind of hash of the picture when the user uploads it, and then use this to know if the user already has this image (maybe send the hash as an Etag?) I have found this answer and this answer that explain the logic pretty well, but I have 2 questions: Is it possible to send an Etag in Google App Engine? Has anyone implemented such logic, and/or is there any code snippet available?

• VB.NET: Scrollbar "button"?

  - by Omega

  I plan on using a scrollbar for, well, scrolling an image. The image is 200x500, however, the only visible area is 200x250. So I set the max value to 250, and the min value to 0. The idea is that if I drag the scrollbar's button to the bottom, 250 pixels will have moved for the image, right? But wait, the scrollbar's button is.... very small. And the scrollbar is actually pretty long. Is there a way to make the scrollbar's button longer?

• Which Joomla module can be used to show articles with thumbnail?

  hi guys, I am trying to implement ja_nickel joomla template in my site. here is the preview of ja_nickel template: http://demo.ijoomlahost.com/ja-nickel/ I want my latest news articles to be displayed in the place of top information block.

I want image, title and content in an article but don't know which provides it. OR can we just merge the title and content both of normal article and display the image of article like that?

• Quick Question: How can I make sure the current directory is not changed because of OpenFileDialog?

  - by pecker

  say my application is installed in C:\programfiles\xyz\ I've some setting & other data files (*.dat files) in this directory too. My application uses OpenFileDialog to open an image. Problem is that when ever user browses to some directory (say MyPictures) for an image. The current working directory of the application becomes that directory (MyPictures in this case). After user inputs the image. I do some processing over it and save some values to imagedata.dat which will be located in the path where original application is installed.(C:\programfiles\xyz here ) In my code I'm just using FileStream("imagedata.dat",...,...) without any path prefix before the filename. Problem here is that application is crashing because it is searching for imagedata.dat in 'MyPictures\imagedata.dat'. How can I avoid this?

• How can I draw a log-normalized imshow plot with a colorbar representing the raw data in matplotlib

  - by Adam Fraser

  I'm using matplotlib to plot log-normalized images but I would like the original raw image data to be represented in the colorbar rather than the [0-1] interval. I get the feeling there's a more matplotlib'y way of doing this by using some sort of normalization object and not transforming the data beforehand... in any case, there could be negative values in the raw image. import matplotlib.pyplot as plt import numpy as np def log_transform(im): '''returns log(image) scaled to the interval [0,1]''' try: (min, max) = (im[im > 0].min(), im.max()) if (max > min) and (max > 0): return (np.log(im.clip(min, max)) - np.log(min)) / (np.log(max) - np.log(min)) except: pass return im a = np.ones((100,100)) for i in range(100): a[i] = i f = plt.figure() ax = f.add_subplot(111) res = ax.imshow(log_transform(a)) # the colorbar drawn shows [0-1], but I want to see [0-99] cb = f.colorbar(res) I've tried using cb.set_array, but that didn't appear to do anything, and cb.set_clim, but that rescales the colors completely. Thanks in advance for any help :)

• Expand / Collapse Swimlane (Domain Specific Language) C#

  - by Tejas

  I have multiple swimlanes on the surface, Is it possible to have expand / collapse functionality to these swimlanes?. My swimlanes are going to contain different shapes (Image Shapes), Geometry shape etc. I have tried the nesting of a geometry shpes but it only contains the geometry shapes not image shapes i.e. I have already created a Geometry shape with it's type as a RectangleD and by writing its partial class I have overridden the Expand() and Collapse() methods but to no avail because this particular Shape (Container) going to contain only Geometry shapes and not the Image shapes. Now I am trying to expand / collapse the swimlanes itself. Please let me know if anyone has done this before.

• On site load, how do you wrap all images in a link dynamically using Javascript?

  - by akaii

  I have barely any experience working with DOM and using Javascript, and I have a very specific task that I'm trying to accomplish. Let's say I have an image in my HTML: <img src="foo.jpg" /> When the site loads, I want to take that image (all images in the document, actually), and wrap them in a link: <a href="http://www.foobar.com"><img src="foo.jpg" /></a> What could I use to accomplish this? Google hasn't turned up much for me with regards to this specific task. On load, I can access and iterate all the images in the document... but I'm not sure where to go from there in order to wrap the image in a link.
